Asking whether a MINI Clubman F54 Cooper D Essential Trim is a good car for families, is not easy to answer from a technical point of view. The range of families requirements is wide, so this consideration only considers the common aspects.
The MINI Clubman has 5 seats, which is enough for many families, and also brings a decent trunk with 1250 liters of volume, in which there is still room for luggage even with a stroller loaded. Good conditions for a family car. There are no Isofix brackets installed. These could be used to secure child seats easily and safely.
